Cutaneous syncytial myoepithelioma: A potential pitfall in the differential diagnosis of superfi cial dermal tumors

Erdem Comut* and Nese Calli Demirkan

In the spectrum of myoepithelial tumors of the skin, cutaneous myoepithelioma is composed solely of myoepithelial cells. Cutaneous syncytial myoepithelioma as a rare histological variant of cutaneous myoepithelioma has been fi rst described in the last decade. This tumor is benign and rarely shows recurrence when incompletely resected. In addition to its distinctive common histological and immunohistochemical features, cutaneous syncytial myoepithelioma shares the same changes for most cases in molecular testing (EWS RNA binding protein 1 gene rearrangement). The differential diagnosis of other superfi cial dermal tumors is one of the major diffi culties in the diagnosis of this tumor. In the current study, we present our fi ndings of a 56 year-old woman who was diagnosed as cutaneous syncytial myoepithelioma.
